Apples are loved by people because they are rich in vitamins, sugars and other nutrients. However, in daily life, many people have encountered apples that have become dry after being stored for a long time. Such apples have lost most of their nutritional value, and their bacterial content may even be greater than their nutritional content. Therefore, people need to learn some scientific methods of storing apples to better prevent them from drying out. What to do if the apple is dry (1) If apples are stored for a long time and become dry, do they still have nutrition? Yes, but the nutritional value is definitely reduced. First, the iron is oxidized, and the absorption is not as good as fresh ones. Then, after being left for a long time, the bacteria content in the apple will be higher than that of fresh ones. Then, the dried apples made by the process also lack some substances that fresh apples do not have. These substances are produced by the reaction between sunlight and the apple, and are nutrients that are not easily produced in the human body. (II) Storage methods of apples First, select the ripe apples without mechanical damage, soak them in 3% salt water for 6 minutes, then take them out to dry, wrap them with soft white paper, and store them according to the following two methods: 1. Water tank storage method First, clean the water tank and dry it, then place it in a cool place. Place a can filled with clean water at the bottom of the tank without covering it with a lid. In the morning when the temperature is low, put the wrapped apples into the jar layer by layer. When the jar is full, seal the mouth with a piece of plastic film. This storage method can store apples for 5 months with a good quality rate of over 90%. 2. Wooden box storage method Place several layers of paper on the bottom and around the box, and put 10 wrapped apples into a small plastic bag. In the morning when the temperature is low, place two bags full of apples face-to-face in the box. Fill the box layer by layer, cover it with several layers of paper, then seal it and place it in a cool place. This storage method can generally store apples for 6 months. |
